'lb all /r/w//t it muy concern.'

Be it known that we, ROBERT Farines and Ciraiuais T. CLARK, citizens of the United States, residing' at Cleveland, in the county ot Cuyahoga and State of Ohio, have inrentcd certain 'new and useful improveA monts in VElectric Radiator-Electors, of which the Afollowing is a specification.

This invention relates to electrically heated radiators. in which local electrical devices arl` used lor heatingwater in a radiator or the lilic, and it is characterized by iniproreunails with respect to the construction and arrangement of the heating units with respect to other parts of the radiator in order to ell'ect a circulation of the water and an advantageous location of the heating devices.

The inventionis illustrated in the accompanying` drawing, which is a side elevation, partly in section, ot a radiator provided with the heater.

Referringspecifically to the drawings: l indicates a radiator of any suitable construction. having vertical tubular or hollow members, and a hollow horizontal base l2 extending" across and communicating with the lower ends or the radiator sections.

Within this lower cross connection is located a tube 2 which extends through a gland 'T at the end of the radiator. The iriner end ot' this tube opens into the hollow member 12, and the tube is surrounded by another tube 4: which incluses the heating coils Z3 located between the tubes 2 and 4 and arranged to heat both of them. A screw plug 13 may be used to close the end ot' theI coil tube il.

The outer end of the inner tube 2 is connected by an elbow 5 to the lower end of an upright pipe i which is connected at its up per end by an elbow 14 to the top cross connection ot' thel radiator sections. rlhis tube (i is surrounded by a heating coil l0 'inclosed in a tube ll. A switch in the box S controls the circuit connections 9 to the respective coils. aml is preferably so arranged that either or both of the coils may be used according to the decree oli heat required.

'lhe water in the lower cross chamber of the radiator is heated by the coil 3, at both the surl'acn ot' the pipe 2 and the pipe el, and thu water in the riser G is heated bythe coil Il). This induces a circulation, the hot water llowiug through the ltube 2 and up through the tube (5 and returning through the radiator sections to the lower chamber.

'lhe coils can be readily removed when de-v sired by looseningv the gland? andtlisconmeeting the upper elbow l2, Without disassemhlingr the radiator sections.

What we claim as new is:

l. A heater comprising radiator having a lower chamber, a pipe projecting into said chamber, and opening at its inner end, a vertical pipe connected to the outer end of said pipe and to the top of the radiator,

-and a heating' coil surrounding the first mentioned tube, within said lower chamber. :2. A heater comprising a radiator having a lower chamber. an inner tube projectin into said chamber and open at its inner en an outer tubeI surrounding said inner tube within said chamber. a heating coil located between the inneand outer tubes, and a pipe connection vtroni the outer end of the inner tube. to the upper` 'part ofthe radiator. 3. .i heater comprising a radiator having,l

a lower water chamber, tube projecting Joux A. lloaluHAnDT, l). (l. lll-inn.
